Question

The ratio of income of a and b is 3:4 the ratio of their expenditure is 2:3and each save 200 find the income of A and B

Answer 1

Answer:

A income = 600

B income = 800

Step-by-step explanation:

Let say total income = x

A income  = 3x/7

Bincome = 4x/7

As each saves rs 200 so total saving = 200+200 = 400

Total expenses = x -400

A expense = (2/5)(x-400)

(3x/7) - (2/5)(x-400) = 200

15x - 14(x-400)=200*35

15x - 14x + 5600 = 7000

x = 1400

A income = 3x/7 = 3*1400/7 = 600

B income = 4x/7 = 4*1400/7 = 800
